:Issued: 2018 Mar 05 0116 UTC# Prepared by the US Dept. of Commerce, NOAA, Space Weather Prediction Center# Product description and SWPC web contact www.swpc.noaa.gov/weekly.html## Weekly Highlights and Forecasts#Highlights of Solar and Geomagnetic Activity 26 February - 04 March 2018
Solar activity reached low levels on 02 Mar due to an isolated C1 flare from Region 2700 (N06, L=328, class/area=Cro/30 on 26 Feb), which was the only active region with sunspots this period. Solar activity was very low throughout the remainder of the period and no Earth-directed CMEs were observed. No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 26-27 Feb and 03 Mar and moderate levels were observed on 28 Feb and 01-02 Mar. Normal levels were observed on 04 Mar.

Geomagnetic field activity reached active and G1 (Minor) geomagnetic storm levels on 27 Feb due to the influence of a negative polarity CH HSS. Generally quiet and quiet to unsettled conditions wereobserved throughout the remainder of the period.

Forecast of Solar and Geomagnetic Activity 05 March - 31 March 2018
Solar activity is expected to be very low throughout the outlook period. No proton events are expected at geosynchronous orbit. The greater than 2 MeV electron flux at geosynchronous orbit is
expected to reach high levels on 18-25 Mar and moderate levels are expected on 17, and 26-30 Mar. Normal flux levels are expected for the remainder of the outlook period. Geomagnetic field activity is expected to reach G1 (Minor) geomagnetic storm levels on 18, 22 and 26 Mar due to the influences
of multiple recurrent, CH HSSs. Active levels are expected on 15-17 and 21 Mar with generally quiet and quiet to unsettled conditions likely through the remainder of the outlook period.
